Question 3 A psychological test has scores that range from 0 to 10 (whole numbers only). The stable range is given by scores ranging from 3-8 (inclusive); the group scoring less than 3 are labeled as Low Risk, while those with a score greater than 8 are labeled as High Risk. In a certain population of interest the probabilty that a person is pschologically stable is 86 % , and the probability that a person is from the High Risk group is 4%. A random sample of 10 people is taken from this population What is the probability that at least 2 people are NOT from the High Risk group? a) b) What is the probability that fewer than 3 people are from the Low Risk group?
